SPECIFICATION forming part of Letters Patent No. 486,641, dated November22, 1892.

Application filed July 2, 1892. Serial No. 438,748. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN W. GR-ANTLAND, a citizen of the United States,residing at the city of Philadelphia, in the county of Phila delphia andState of Pennsylvania, have in- Vented certain new and usefulImprovements in Hooks, of which the following is a specification.

My invention relates in general to hooks that are employed in connectionwith eyes for fastening garments and other like articles; and it relatesmore particularly to that class of such hooks which are provided withmeans for preventing the accidental detachment of the eyes therefrom andwhich are commonly designated safety-hooks.

The principal objects of my invention are, first, to provide a simple,durable, eflicient, and com paratively-inexpensive hook; second, toconstruct and arrange the parts of a hook for operation in such mannerthat the hook is self-contained, meaning by that term that the eye maybe attached and detached with out causing any of the parts of the hookto project beyond the general outline thereof, and, third, to provide asafety-hook that is not rendered inoperative by the accidental bendingof the point of the bill, which frequently occurs in practice.

My invention consists of the improvements hereinafter described andclaimed.

The nature, scope, and characteristic features of the invention will bemore fully understood from the following description, taken inconnection with the accompanying drawings, forming part hereof, and inwhich- Figure l is a top or plan view of a hook, embodying features ofmy invention and illustrating the same in connection with an ordinaryeye. Fig. 2 is a similar view of the under side of the hook; and Fig. 3is a side elevation of the hook and eye illustrated in Figs-1 and 2,showing the bill provided upon the under side thereof with a rampart orprojection, and also showing a tongue carried by the shank and adaptedto co-operate with the rampart or projection.

In the drawings, a is a hook comprising a doubled wire, having thedoubled portion thereof curved to form a bill a, provided with adownwardly-projecting rampart a and having the doubled portion thereofalso curved to form eyes a for the reception of the thread, by means ofwhich the hook is commonly attached to place. One extremity of thedoubled wire after forming a threadeye extends forward and forms astraight tongue or latch a that is adapted to co-operate with therampart or projection a in the manner hereinafter explained. In use theeye I) may be inserted beneath the point of the bill a and then drawnforward past the rampart or projection a into the position illustratedin the drawings. During this operation the tongue or latch a yieldsslightly in a downward direction, thus permittingthe eye I) to pass therampart or projection a and then returns to place in contact with theprojection or rampart a in order to prevent accidental detachment fromthe hook and eye. The eye I) may be readily detached from the hookwhenever it becomes necessary or desirable so to do by the simpleoperation of pushing the eye I) in a reverse direction between therampart or projection a and its compleinental latch or tongue a.

Among the many obvious advantages 'pos sessed by a hook constructed inthe manner hereinabove described the following may be particularlymentioned: First, the tongue or latch a does not project beyond thegeneral outline of the hook, even during the operation of inserting theeye I; therein, so that the hook is self-contained; second, the bill amay be bent upward or away from its shank of, as frequently occurs inpractice, without interfering with or injuriously effecting the efficiency of the devices for preventing accidental detachment of the eye,because the resiliency of the tongue or latch a causes the same tofollow up and co-operate with the projection or rampart a in its newposition; third, the doubled-wire bill a presents a smooth extremitythat does not tend to cut or otherwise injure the article to which thehook is applied; and, fourth, the two wires forming the rampart orprojection a are brought close together in the manner illustrated inFig. 1 and form by reason of their cylindrical orapproximately-cylindrical shape a concave seat, against which normallyen gages the intermediate portion of the tongue upward and forward fromthe thread-eyes and having its free extremity working in the openingbetween the wires of the curved neck portion of the bill and having itsintermediate portion normally engaging said seat, substantially as andfor the purposes set forth.

In testimony whereof I have hereunto set my signature in thepresenceoftwo subscribing witnesses.

JOHN W. GRANTLAND.
